Maybe the bodied Reimu is making her own home, and the arrogant deibu is taking for granted it will be for her, so the bodied one, in anger, kicks the box in her face.

*testing quoting*
The Bodied one could be using more than 1 box to make her own house, it's not weird, many hobos do that, since it's not that common to find human sized boxes.
